Infrared light-absorbing Polyfluorene(PFO) converts the light into visible light. The PFO in dye sensitized solar cell provide visible light for dye. And the highly crystallized polyfluorene provides light path and it enhances the conversion efficiency of DSSC. Here, we investigate the relationship between crystallinity of the PFO and the energy conversion efficiency of DSSC. The Polyfluorene copolymer; (Poly(9,9)-di-n-hexyl fluoreneyl-2,7-diyl) and (Poly(9,9-di-n-octyl fluorenyl-2,7-diyl)) layer were coated on the FTO glass and the crystalline was observed by polarized spectroscopy. |
